The work

What Optinize handles.

01

Sender inventory

Identify ESPs, CRMs, transactional platforms, support tools and hidden third-party senders.

02

Safe configuration

Remove SPF lookup risk, validate DKIM signing and align visible From domains correctly.

03

DMARC enforcement

Deploy reporting, identify unknown traffic and move from monitoring toward quarantine or reject safely.

Best fit

This is usually worth solving when:

  • DMARC is missing or still at p=none
  • SPF contains too many lookups or stale includes
  • Different tools send with inconsistent alignment
  • You need a safe enforcement plan without interrupting mail

Get a precise diagnosis before committing to a project.

Share the domain, platform and symptom. We will tell you what we can verify, what remains uncertain and the next sensible step.
